CROSS REFERENCE

This application claims the priority of Chinese Patent Application No.201610234432.8, entitled “Packing boxes of liquid crystal panels”, filedon Apr. 15, 2016, the disclosure of which is incorporated herein byreference in its entirety.

FIELD OF THE INVENTION

The present invention relates liquid crystal display technology field,and more particularly to a packing box of liquid crystal panels.

BACKGROUND OF THE INVENTION

Generally, the manufacturing process of the liquid crystal devices(LCDs) relates to assemble the components, such as a glass panel, a maincontrol circuit, and a housing. The above components are manufacturedand package first, and are assembled in subsequent manufacturingprocesses. After the liquid crystal panel is manufactured and ispackaged within the packing box, the packing box is transported tocorresponding assembly factory.

The packing material of the box includes an outer paper box and aninternal packing box. Usually, the packing boxes are stacked together.To enhance the assembly time, the directions of the packing boxes haveto be the same. However, such stacking configuration may result in thatoperators may not be able to recognize the directions, which slows downthe packing speed.

SUMMARY OF THE INVENTION

The present disclosure relates to a packing box of liquid crystal panelsto enhance the packing speed.

In one aspect, apacking box of liquid crystal panels includes: an outerbody and two bearing trays received within the outer body, each of thebearing trays includes a body and a plurality of clips arrangedperiodically, the body includes a first surface and a second surfaceback to the first surface, the clip protrudes from the first surfacetoward the second surface, the clip includes a recess portion on a topportion of the first surface and a protrusion portion on the secondsurface, a hub is arranged on a bottom of the recess portion, the hubextends toward an internal of the protrusion portion, when the twobearing trays are stacked, the protrusion portion of the bearing trayson a top layer inserts into the hub of the other bearing tray to abutagainst a wall of the hub.

Wherein cross sections of the hub and the clip are crisscross-shaped orequilateral-triangular.

Wherein the body and the clips are integrally formed by injectionmolding.

Wherein the hub and the protrusion portion are conical columns.

Wherein a plurality of positioning slots are arranged on the firstsurface of each of the bearing tray, and the clips are configured tosurround the positioning slots.

Wherein a wall is arranged around a rim of the second surface of each ofthe bearing trays, when the two bearing trays are stacked, the wall ofthe bearing tray on the top layer covers the rim of the bearing tray ona down layer.

Wherein the bearing tray is made by mixing plastic material and organicmaterial.

Wherein the clips are uniformly arranged in a rim of the body.

In view of the above, the hub of the bearing tray inserts to theinternal of the protrusion. When the two bearing trays are stacked, theprotrusion portion of the bearing trays on the top layer inserts intothe hub of the other bearing tray to abut against a wall of the hub,which increases the stability therebetween. In addition, the crosssections of the hub and the clip are of symmetrical shapes, such ascrisscross-shaped or equilateral-triangular. Due to the symmetricalshape, the hubs may engage with the protrusion portion easily, whichsaves the packing time.

FIG. 2 is a lateral view of the two stacked bearing trays of FIG. 1.

FIGS. 3 and 4 are schematic views showing the bearing trays of FIG. 1from two different angles.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Embodiments of the present invention are described in detail with thetechnical matters, structural features, achieved objects, and effectswith reference to the accompanying drawings as follows. It is clear thatthe described embodiments are part of embodiments of the presentinvention, but not all embodiments. Based on the embodiments of thepresent invention, all other embodiments to those of ordinary skill inthe premise of no creative efforts obtained, should be considered withinthe scope of protection of the present invention.

Referring to FIGS. 1, 2 and 3, the packing box of liquid crystal panelsis configured for carrying the liquid crystal panel. Specifically,before the liquid crystal panel, modules, and the housing are assembledto be the LCD, the liquid crystal panel is transported to the assemblylines. During the transportation, the liquid crystal panel has to beprevented from being damaged. In addition, in order to facilitate theunpacking of the liquid crystal panel, the bearing tray is adopted. Thepacking box includes an outer body (not shown) and two bearing trays 10received within the outer body. Each of the bearing trays 10 includes abody 11 and a plurality of clips 12 arranged periodically. The body 11includes a first surface 111 and a second surface 112 back to the firstsurface 111. The clip 12 protrudes from the first surface 111 toward thesecond surface 112. In addition, the clip 12 includes a recess portion121 on a top portion of the first surface 111 and a protrusion portion122 on the second surface 112. A hub 123 is arranged on a bottom of therecess portion 121. The hub 123 extends toward an internal of theprotrusion portion 122. The two bearing trays 10 are stacked. Theprotrusion portion 122 of the bearing trays 10 on the top layer insertsinto the hub 123 of the other bearing tray 10 and abuts against the wallof the hub 123. That is, the recess portion 121 engages with the hub123.

In the embodiment, the bearing tray 10 is of rectangular plate, and isformed by injection molding. The body 11 and the clips 12 are integrallyformed such that the clip 12 is of hollow cylinder. The recess portion121 is arranged on the top portion of the first surface 111, and theprotrusion portion 122 is arranged on the second surface 112. Thebearing tray 10 is made by mixing plastic material and organic materialso as to enhance the plastic-absorption capability.

Referring to FIG. 3, the clips 12 are arranged in a rim of the body, andmay be arranged in anuniform distribution or in a configuration inaccordance with the carried weight to effectively support the bearingtray 10. In addition, the locations of the clip 12 may be configured inaccordance with the weight to be carried by the bearing tray 10. The hub123 and the protrusion portion 122 are conical columns. When the twobearing tray 10 are stacked, the protrusion portion 122 of the bearingtray 10 on the top layer may insert into the hub 123. The outside of theprotrusion portion 122 abuts against the inside of the hub 123. As such,the protrusion portion 122 of the bearing tray 10 may not abut againstthe first surface of the bearing tray on the down layer. In addition,the outside of the protrusion portion 122 partially overlaps with theinside of the hub 123, which increases the stability therebetween.

Further, the cross sections of the hub 123 and the clip 12 are ofsymmetrical shapes, such as crisscross-shaped or equilateral-triangular.Due to the symmetrical shape, when the bearing trays are stacked, thedirections of the bearing tray may be ignored when the number and thelocations of the clips are the same, which reduces the packing time.

Further, a plurality of positioning slots 13 are arranged on the firstsurface 111 of each of the bearing tray 10. The clips 12 are configuredto surround the positioning slots 13. In the embodiment, a wall 113 isarranged around a rim of the second surface 112 of each of the bearingtrays 10. When the two bearing trays 10 are stacked, the wall 113 of thebearing tray 10 on the top layer covers the rim of the bearing tray 10on the down layer.

Above are embodiments of the present invention, which does not limit thescope of the present invention. Any modifications, equivalentreplacements or improvements within the spirit and principles of theembodiment described above should be covered by the protected scope ofthe invention.
